摘要
系统建模仿真作为空降车辆着陆缓冲研究的重要手段,用于仿真着陆缓冲阶段的气囊排气压缩、车辆缓冲过载、姿态变化及结构冲击响应。从系统建模、匹配设计、半实物试验、空投适应性4个方面进行评估,综述现有研究应用的理论、方法和研究结论。对目前仿真模型求解效率,结构应力和气囊仿真准确度,车辆与气囊参数匹配,半实物试验,空投适应性评估等问题进行分析总结并提出进一步的研究方向。
As an important method for studying the landing buffer of airborne vehicles,system modeling and simulation were used to simulate the processes of airbag exhausting compression,vehicle buffer overload,attitude change,and structural impact response during landing buffer stage.The existing theories,methods,and research conclusions in four aspects:system modeling,matching design,semi-physical experiments,and air-dropping adaptability evaluation were summarized.The current problems of simulation efficiency,simulation accuracy on structural stress and airbag exhausting,parameter matching of vehicle and airbag,semi-physical experiments,and air-dropping adaptability evaluation were analyzed and summarized,then,further research directions were proposed.
